Count me as another Fluke fan, I started with the Fluke 77 in the
Navy, and as a result bought a Fluke 77 III. It's the one piece of
test equipment that I use the most.
I'm not sure where Richard lives, but anyone looking into
Oscilloscopes or meters that lives close to a Fry's might want to
consider checking them out. They're where I got my Fluke 77 III and
Tek TDS-220 from, and at least the one near me seems to always have a
Something else I added to my assortment of test equipment in the last
year or so was something I've always wanted, though I have to
question my need for it, and that's a clamp-on Amp meter.
The next pieces of test equipment I'm likely to be looking at will be
a Variac and a Oscillator.
